The former bookkeeper of City View Charter School pleaded not guilty Monday on charges that she stole about $90,000 from the school.

Michelle Wheeler, 37, pleaded not guilty to six counts of first-degree aggravated theft. Bail was set at $120,000 on the City View case, but Wheeler has to stay in the Washington County Jail until May 10 after pleading guilty to stealing $10,000 from another charity.

City View is Hillsboro's only charter school and receives money from the Hillsboro School District to run innovative programs for children in kindergarten through eighth grade. Wheeler was hired as the charter school's bookkeeper in June 2006 and resigned in December 2007 when board members began questioning school finances.

Wheeler was sentenced April 21 to 20 days in jail and 18 months' probation after pleading guilty to first-degree theft and identity theft. For several years, she operated Safe Harbor, a clothes closet for low-income families, out of her Hillsboro garage. She got grants from several organizations for Safe Harbor, but used the money for personal items and to open an illegal poker room.

Wheeler also pleaded guilty last year to stealing $5,900 from In Defense of Animals-Africa, a Beaverton-based, non-profit group that hired her as bookkeeper.
